In the June 2012 elections, Golden Dawn only got 6.9 percent of the vote. In other words, in less than five months,the party has expanded its support by somewhere in the range of 67-103 percent, depending on which poll you look at.

Ruling party New Democracy, led by Greek prime minister Antonis Samaras, has seen its support collapse to 22 percent from the 29.7 percent of the vote that won it the election in June.

Support for SYRIZA, the leftist, anti-bailout party that has become the top party in the polls since the election, also fell to 25.5 percent in the latest poll – from the 26.9 percent of the vote it garnered in June.

Meanwhile, PASOK, the junior party in the leading coalition, has seen a plunge in popular support as well, from 12.3 percent in June to 6.5 percent in the latest poll.

There have been several signs that support for Golden Dawn is on the rise, but the extent of the gains is significant.

When the survey questioned who would be the best prime minister for the country now, 28% of those interviewed replied Antonis Samaras, against 23% who chose Tsipras while 45% did not indicate anyone. According to the poll, 71% of Greeks surveyed said they were satisfied with the government against 26% who weren't.
